Criteria

Inclusion Criteria:

• Have surgically incurable, confirmed metastatic colon or rectal adenocarcinoma.

• Be male or non-pregnant, non-lactating female subjects ≥ 18 years of age.

• If female, and of childbearing potential, agree to use adequate contraception (as deemed by the investigator) throughout their participation in this study and for 30 days after discontinuation of study medication.

• If, female of childbearing potential, have a negative pregnancy test prior to the start of the study.

• Have a life expectancy of at least 6 months.

• Have radiologically or clinically measurable disease for response assessment. Presence of ascites or pleural effusion(s) are not acceptable as single sites of response assessment, but may be present if dimensional or other discrete measurable disease is present for evaluation.

• Have an ECOG Performance Level of 0-2 (or Karnofsky of 100-70). A lower ECOG or Karnofsky is acceptable only if clearly due to non-oncologic conditions (e.g., prior paraplegia from polio).

• Have had no prior chemotherapy for established, metastatic disease. (Subjects may have received adjuvant chemotherapy with fluoropyrimidine therapy).

• Have at least 6 months elapsed since prior adjuvant 5-FU or CPT-11 therapy, or Mitomycin C or nitrosourea therapy.

• Have had at least an 8 week interval since any prior radiation therapy or 4 weeks since any major surgery.

• Have recovered from any toxicities resulting from prior therapies (except for alopecia).

• Adequate renal, bone marrow, liver function defined as serum creatinine less than 1.5 times the upper limit of normal, serum bilirubin less than 2 times the upper limit of normal, ANC greater than 1.5 x 109/L, Platelet count greater than 90 x 109/L, SGOT (AST) and SGPT (ALT) less than 3 times the upper limit of normal.

Exclusion Criteria:

• Failure by the subject or the subject's legal representative to sign the Informed Consent.

• An inability to obtain Informed Consent because of psychiatric or complex medical problems.

• Have concurrent infection including diagnoses of FUO or evidence of possible central line sepsis (subjects must be afebrile at the start of therapy).

• Have unstable oncologic emergency syndromes: superior vena cava (SVC) syndrome, rising bilirubin needing stent placement, spinal cord compression, progressive brain metastases, active bleeding, hypercalcemia, etc.

• Have unstable medical conditions such as acute coronary syndrome, cardio-vascular accident within the previous 12 months (such as transient ischemic attacks, accelerated hypertension), etc.

• Have cerebellar neurologic syndromes such as Parkinson's disease, multiple sclerosis, and amyotonia.

• Have a known intolerance to fluoropyrimidine (5-FU, Capecitabine, Floxuridine, UFT) therapy (dihydropyrimidine dehydrogenase deficiency).

• Patients with vomiting, diarrhea, or nausea of grade greater than 1.

• Received any investigational drug or agent/procedure, i.e. participation in another trial within 4 weeks before beginning treatment with study drug.
